Balances and weighing scales are a part of any and every lab. They have a myriad of applications from high school science labs to highly advanced research labs, from your local grocery store to largescale machine manufacturing units.
Weighing balances are known to have been in use from 2000 BC due to their oldest depictions from the Indus Valley civilization. Since then, they have stood as a symbol of justice and fair trade, ensuring that every buyer and seller, giver and receiver have a common ground and mutual understanding.
Weighing balances that were originally used had a beam with a fulcrum in the center and stones for weights. Stones of equal known weights were used as a common point of reference. Today, each nation is obliged to follow a standard convention of predefined weights and units.
Scales today rarely use actual weights to measure the samples by balancing the pans on both sides. There are many different mechanisms for weight measurement and the most commonly used weighing principle is where the system counters the weight of the sample object by the current passed through an electromagnetic coil within the device. Another common method is to use Hooke’s law on a spring. Here, the extent to which the spring stretches when an object is hooked onto it is proportional to the weight of the object. Many other methods also exist, making use of different physical properties.
The scales too have come a long way. Some of the balances that are available in the industry today are analytical balances, portable balances, top-loading balances, micro and semi micro balances, floor scales and platform scales.They are classified on the basis of their application and usage as well as their range of measurement.
They may be used to measure tiny samples of tissue, samples of chemical powders, animals in veterinary clinics, loads to be shipped on trucks etc. Each scale has a purpose. Each one is built to suit a particular requirement. This also makes it all the more important to know what the user’s requirements are and chose the appropriate balance to suit the need. Each balance differs in terms of accuracy, readability, range of measurement and overall cost.
In order to maintain a good pair of scales and get the best out of them, it is necessary to take good care of them and to keep them free from outside interference and misuse. Scales may be placed on anti-vibration tables to keep external vibrations from giving us wrong measurements. Additionally, they may also be placed within a draft shield for protection from outside currents.
We realize that each lab or studio has unique needs and so we can help you by coming up with anti-vibration techniques specifically suited to your home or work environment. We at www.antivibrationtable.com offer you a customized solution to your problem.
